    iPhone for the China trip - keeping it charged.

    Keeping the iPhone powered while traveling

    When I was at home or at work, it was simple enough to plug the iPhone
    in somewhere to quickly top off the battery, but when traveling or
    running around all day, it’s too easy to run the battery down. What do
    you do when the phone doesn’t have a removable battery?

    Part 1 - Mophie Air case
    http://mophie.com/

    This is a 1200mAh battery, built into a case. It adds a bit of bulk to
    the phone, but I have found the advantage of having a charged phone
    all day is worth it.  It is sufficient to keep the phone going all day
    without running the battery down all the way. The battery in the
    Mophie case is enough to charge the iPhone %60 of charge. I turn the
    case battery on when I’ve run the battery down to 40%.

    The only downside is the cover piece that fits over the volume
    buttons. There is a very thin and narrow piece of plastic which seems
    to be prone to cracking. I read online that this is a very common
    problem. I “fixed” my case by cutting off the broken piece, and then
    gently sanding around the edges to smooth them out. I tried gluing the
    pieces together with some super glue, but the broken bit refused to be
    glued. I was afraid if I left it broken and loose, it might crack the
    piece in a more even inconvenient place.

    Part 2 - The Just Mobile Gum Pro 4400mAh external battery

    This is an external battery that will charge your iPhone 2.4 times.
    I’m not sure how many times it can charge the Mophie Case plus iPhone
    combo, but it is enough to give many more hours of extra use. The
    battery has a mini-USB plug to charge it, and a standard USB plug to
    plug the phone or Mophie case into. The added benefit is that if you
    have any other devices that charge off a USB plug, you can use the
    battery with it as well.

    Part 3 - Plug Adapters
    I got a China power plug adapter so that I can plug my regular iPhone
    USB charger into the Chinese wall outlets. This adapter is also common
    with the Australian-New Zealand plugs. It looks like a U.S. plug with
    the prongs rotated slightly to form a V. I have been fortunate to find
    that the hotels we’ve been staying at have universal wall outlets. I
    have only needed to use the adapter in one hotel. Some people will
    tell you that you need a voltage converter. You only need a voltage
    converter for devices that aren’t euro-asia friendly and will only run
    on U.S. voltage (110-120v). Many chargers, like the iPhone USB
    charger, is rated for 100-240v, so it can be used with a plug adapter.

    I also made a modified extension cord, so that I could use more than
    one US device with the adapters.
